Kiernan, Matthew C., Guglielmi, Jean-Marc, Kaji, Ryuji, Murray, Nicholas M. F., Bostock, Hugh
Multiple nerve excitability measurements were used to investigate axonal membrane properties of patients diagnosed with multifocal motor neuropathy (MMN). Six patients were selected, all with...
Abnormal axonal inward rectifier in streptozocin-induced experimental diabetic neuropathy (2001)
Yang, Qing, Kaji, Ryuji, Takagi, Tsunekazu, Kohara, Nobuo, Murase, Nagako, Yamada, Yuichiro, ...
In order to explore the pathophysiology of diabetic neuropathy, we studied serial changes of axonal excitability in 20 adult Wistar rats with streptozocin-induced diabetes using the technique of...
Abnormal premovement gating of somatosensory input in writer's cramp (2000)
Murase, Nagako, Kaji, Ryuji, Shimazu, Hideki, Katayama-Hirota, Mari, Ikeda, Akio, Kohara, Nobuo, ...
One characteristic of focal dystonia is the sensory trick, by which sensory input to a certain area of the body can reduce abnormal contractions in muscles nearby. This suggests that adjusting the...
Activity-dependent conduction block in multifocal motor neuropathy (2000)
Kaji, Ryuji, Bostock, Hugh, Kohara, Nobuo, Murase, Nagako, Kimura, Jun, Shibasaki, Hiroshi
Patients with multifocal motor neuropathy may complain of muscle fatigue, even though the degree of conduction block assessed at rest has improved with treatment. To explore the mechanism involved,...
